Performance of the quantitative pupillary light reflex and neurological pupil index for predicting neurological outcomes in cardiac arrest patients: A systematic review and meta-analysis.

Background: The performance of quantitative pupillary light reflex (qPLR) and the neurological pupil index (NPi) was used to predict neurological outcomes in cardiac arrest (CA) patients.

Methods: Eligible studies on the ability of the qPLR and NPi to predict neurological outcomes in CA patients were searched from the PubMed and China National Knowledge Infrastructure databases until July 2023. The pooled odds ratio (OR) and its 95% confidence interval (95% CI), area under the curve, sensitivity analysis, and publication bias were analyzed via Stata 14.

[Ammonium Adsorption Characteristics in Aqueous Solution by Titanate Nanotubes].

Titanate nanotubes (TNTs) were synthesized via a hydrothermal method using P25 and NaOH as the raw materials. The composition and morphology of the nanotubes were characterized by X-ray diffraction and transmission electron microscopy. The adsorption characteristics and the rules of ammonium in aqueous solutions were tested in the static system.
